Keith Marshall has been through two straight seasons full of injuries and is entering his senior season with the Georgia Bulldogs in 2015.
They may or may not have a big role planned for him, but he is more than capable of making an impact if he is given consistent playing time. There is a video going around that features the running back saying he feels better than ever since he started playing for Georgia, which is a very good sign.
Throughout the three seasons that Marshall has played, he has carried the football 185 times for 1,029 yards and nine touchdowns.
